質問 1：
Your company is developing a new database application in Oracle Cloud Infrastructure. You need to test application functionality including a hardware failure scenario. Since the application is still in the development phase, you want to minimize infrastructure costs.
Which database service deployment option meets this requirement?
A. Autonomous Data Warehouse (ADW) system as it provides auto fail over functionality
B. two node bare metal system with data guard enabled
C. single node bare metal system
D. two node real application cluster (RAC) system
正解：D

質問 2：
The Oracle Cloud Infrastructure Block Volume service lets you expand the size of block and boot volumes. Which three options below can you use to increase the size of your block volumes?
A. Take a backup of your existing volume and restore from the volume backup to a larger volume
B. You can only expand block volumes and not boot volumes
C. Expand an existing volume in place with online resizing
D. Expand an existing volume in place with offline resizing
E. Clone an existing volume to a new, larger volume

質問 3：
Which statement Is true about Data Guard implementation in Oracle Cloud Infrastructure (OCI) bare metal and virtual machine database systems?
A. Primary and standby database versions and editions need not be Identical.
B. Both database systems must be in the same compartment.
C. Primary and standby databases must be in the same OCI region.
D. Database systems need not be the same shape type (e.g, primary database can be a virtual machine, and standby database a bare metal shape, and vice versa).
正解：B

質問 4：
Which service is NOT supported by Oracle Cloud Infrastructure CLI?
A. load balancer
B. database
C. compute
D. block volumes
正解：D

質問 5：
Which two statements are true about restoring a volume from a block volume backup in Oracle Cloud Infrastructure Block Volume service?
A. You can restore a volume from any full volume backup but not from an Incremental backup.
B. You can restore a block volume backup to a larger volume size.
C. You can restore a volume to any availability domain within the same region where the backup is stored.
D. You can restore only one volume from a manual block volume backup.
E. You can only restore a volume to the same availability domain in which the original block volume resides.

質問 6：
You need to set up instance principals so that an application running on an instance can call Oracle Cloud Infrastructure (OCI) public services, without the need to configure user credentials.
A developer in your team has already configured the application built using an OCI SDK to authenticate using the instance principals provider.
Which is NOT a necessary step to complete this set up?
A. Deploy the application and the SDK to all the instances that belong to the dynamic group.
B. Create a dynamic group with matching rules to specify which instances you want to allow to make API calls against services.
C. Create a policy granting permissions to the dynamic group to access services in your compartment or tenancy.
D. Generate Auth Tokens to enable instances in the dynamic group to authenticate with APIs.
正解：A

質問 7：
You have two NFS clients running in two different subnets within the same Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN). You have created a shared file system for the two NFS clients who want to connect to the same file system, but you want to restrict one of the clients to have READ access while the other has READ/Write access. Which OCr feature would you leverage to meet this requirement?
A. Use File Storage NFS Export Options to control access for the NFS clients
B. Use OCI Identity Access Management to control access for the NFS clients
C. Use NFS security to control access for the NES clients
D. Use VCN security rules to control access for the NFS clients
正解：A

質問 8：
You are designing a shared storage solution for your company in Oracle Cloud Infrastructure. The proposed storage solution should allow users to create a hierarchical structure (similar to the directory structure in Linux or Windows based systems). The solution should provide data encryption and a large amount of storage space.
Which would be the best implementation strategy?
A. Use block storage. Create and attach a large block storage volume to one compute instance. Assign a public IP to the compute instance. Store data on the block storage and access it by connecting to the compute instance.
B. Use object storage. Create multiple namespaces with one bucket each. Make the buckets publicly accessible.
C. Use file storage service. Create a file system and a mount target. Share the private IP of the mount target.
D. Use object storage. Create a single namespace and multiple buckets to create the hierarchical directory structure.
正解：C

質問 9：
You are the Cloud Architect of a company, and are designing a solution on Oracle Cloud Infrastructure where you want to have all your compute instances resistant to hardware failure.
Which two are recommended best practices to achieve the requirement on Oracle Cloud Infrastructure? (Choose two.)
A. Attach block volumes from different Availability Domains to compute instances in different Availability Domains for high availability.
B. Create backups of your block volumes that are associated with compute instances in different regions.
C. Create a custom image of your system drive each time you change the image.
D. Design your system with redundant compute modes in different Availability Domains to support the failover capability.
